WHAT YOU SHOULD ALREADY KNOW...
In order to get the most out of this course, it expected that you should have attended the, 'Foundations: The Language of SAS' and 'Data Step Techniques: The Language of SAS' courses (or comparable course of study), covering topics including:
- Use of Global statements e.g. LIBNAME FILENAME and OPTIONS
- Use of functions to transform character data (e.g. SCAN, FIND, SUBSTR)
- Use of functions to transform numeric data (e.g. CEIL, INT, FLOOR, ROUND)
- Use of functions to transform dates (e.g. DAY, MONTH, YEAR, INTCK)
- KEEP and DROP to select variables
- IF and WHERE statements to select observations
- Conditional Processing with IF-THEN-ELSE
- Iterative DO Loops
- Conditional Do Loops - DO WHILE, DO UNTIL
- Compile-Time statements (e.g. LENGTH, RETAIN)
- Combining Data Sets vertically and horizontally
- Summarising data with the FREQ, MEANS and TABULATE procedures
